7.9 Analog output X63 (0(4)...20 mA)
The active analog output X63 (0(4)...20 mA) is used to deliver the current output or
another system value.
The output value can be determined using the OutValuSelection parameter.
If a voltage signal is required, it can be made available by connecting a resistor (max.
500 ς). The settings are to be made on the load controller / configuration / analog
output.
The load controller only outputs the sensor data actually used (temperature limiter or
control). Only Pt1000 / Ni1000 can be output, independent of usage.
Parameter OutValuSelection (Load / Load 0 / O2 / Pos Air / Pos Fuel / Pos Aux1 /
Pos Aux2 / Pos Aux3 / Speed VSD / Flame / Temp Pt1000 / Temp
Ni1000 / Temp Pt100 / Temp X61 / Press X61)
Load output Load appears after the internal fixed setting (see table below). If other
alternative settings of load output occur, the scalable parameter Load 0 can be used.
Burner OFF 0% 100%
I (mA) 4 4 20
Burner OFF Stage 1 Stage 2 Stage 3

Note!
When resetting the LMV5, the output is set to 0 mA for approx. 30 seconds!
When selecting the other setting values (all with the exception of Load), the output
mode can be changed.
The output values can be scaled.
